Magnetic Monopoles as the Highest Energy Cosmic Ray Primaries
arXiv:astro-ph/9505134 · doi:10.1016/0927-6505(95)00043-7
Abstract
We suggest that the highest energy $ \gsim 10^{20} eV$ cosmic ray primaries may be relativistic magnetic monopoles. Motivations for this hypothesis are that conventional primaries are problematic, while monopoles are naturally accelerated to by galactic magnetic fields. By matching the cosmic monopole production mechanism to the observed highest energy cosmic ray flux we estimate the monopole mass to be .
